Subject: [PATCH 10/10] irqchip/csky: Add support-vector-irq for apb-intc
Date: Tue, 29 Jan 2019 20:24:29 +0800 [thread overview]
Message-ID: <1548764669-16656-10-git-send-email-guoren@kernel.org> (raw)
In-Reply-To: <1548764669-16656-1-git-send-email-guoren@kernel.org>
From: Guo Ren <ren_guo@c-sky.com>
Some socs don't provide pending registers, so we must make the interrupt
controller working at vector mode. Add csky,support-vector-irq to
support this mode in dts.
